195 It is clear that this has nothing to do with the price at which gas is sold nor does it in any way vary the terms of Article XII, in particular clause 12.1, of the Sales Agreement.
196 The Commissioner argues that the words of connection "in relation to", used in s 24(b) of the Act, are broader in scope than, for example, "consideration for the sale". It is said to be a connection of the latter kind which is reflected by his Honour's reasoning. Consideration "in relation to" the sale is sufficiently broad to include payments which are the price paid by the buyer for more favourable terms in relation to the timing of delivery of gas.
197 In Woodside Energy, this Court was concerned with whether losses incurred by the taxpayer in connection with hedging transactions it had entered into in relation to anticipated sales of crude oil were "expenses payable … in relation to the sale" of the oil under s 24(b) of the Act. That case is a far cry from the present. The hedging transactions in that case were made with parties other than the buyers of the oil. Nevertheless, the observations of the Full Court, following those of Dixon J in Archibald Howie Pty Ltd v Commissioner of Stamp Duties (NSW) (1948) 77 CLR 143 at 152, are pertinent. The Full Court observed that "consideration" in s 24(b) of the Act "would not encompass a passing of money or value which does not move the relevant sale" (Woodside Energy at [63]).
198 It may be accepted that the connection between the MLMDQ payments and the sale of gas is less remote than the connection between the hedging contracts and the sales considered in Woodside Energy. Nevertheless, the MLMDQ payment was quite evidently not a quid pro for the delivery of gas. Rather, it was a payment for an agreement to an enhancement of the buyer's rights as to the timing of the delivery of the same quantity of gas.
199 In this regard it is to be noted that s 24(b) of the Act was concerned (as is s 24(1)(b) of the Act after the 2001 amendment), with the consideration receivable in relation to the sale, not the agreement for sale. The ordinary meaning of the word "sale" is a transfer of property in return for a consideration in money or money's worth: Simpson v Connelly [1953] 1 WLR 911; Robshaw Brothers Ltd v Mayer [1957] 1 Ch 125 at 131-132; Sun World International Inc v Registrar, Plant Breeders' Rights (1998) 87 FCR 405 at 406, 412.
200 In some legal contexts, it may be unduly pedantic to distinguish an agreement for sale from a sale. But in the context of s 24 of the Act, the term "consideration" is concerned with the money or money's worth "receivable … in relation to the sale" rather than the consideration moving from each party to the agreement apt to make the agreement for sale binding on the other parties. The focus of s 24 is explicitly upon the consideration receivable by the seller in order to entitle the buyer to a transfer of the agreed quantity of the commodity.
201 Where a long term supply contract obliges the seller to supply a quantity of gas and the buyer to pay an amount for that quantity of gas, the buyer would usually have no entitlement to gas beyond that paid for; and in such a case, the seller would be entitled to recover damages for breach of contract but the seller would not usually be entitled to recover the price payable for the product. Thus, an entitlement in the seller to recover damages for the buyer's breach of contract would not ordinarily be described as an entitlement to "the consideration receivable … in relation to the sale" for the reason that "the sale" has, ex hypothesi, not occurred.
202 Long term supply contracts can be expected to contain provisions which regulate, over the life of the contract, the rights and obligations of the parties in relation to a broad range of commercial risks attendant upon the relationship between the parties. Many such provisions will not be concerned with the price to be paid for the goods to be delivered. A provision which entitles one party to vary the time of completion would not ordinarily be seen as relating to the payment which is necessary to oblige the vendor to complete the transfer of the goods. Reference to the statutory context confirms that this view applies here.
203 Under the Act, the determination of "assessable petroleum receipts" by reference to "the consideration receivable … by the person in relation to the sale" occurs in the context of a scheme whereby tax is imposed on the profit derived from the commercial exploitation of a natural resource. In this context "the consideration receivable in relation to the sale" is readily seen as payment receivable in return for the successful exploitation of the natural resource. Provisions of an agreement for sale which are not concerned with the quantum of money (or money's worth) payable to the seller in order for the buyer to become entitled to receive a particular quantity of petroleum or marketable petroleum product do not bear upon the extent of the exploitation of the natural resource or the profits derived from the commercial realisation of its value. The natural resource available for exploitation and profitable realisation has not been relevantly depleted by what has occurred.
204 Finally, we observe that the fact that the parties may have achieved the same commercial or economic result by varying the sale price of gas for the period 1991 to 2000 rather than providing for the MLMDQ payments to be made in accordance with the relevant provisions of the heads of agreement does not provide any assistance in characterising the MLMDQ payments. As was said in the plurality judgment in the High Court in Federal Commissioner of Taxation v Orica Ltd (1998) 194 CLR 500 at [70]:
[L]ittle or no guidance is offered by considering what other transactions the taxpayer might have made to achieve a commercial result substantially the same as the commercial result said to flow from the making of the Principal Assumption Agreement. No doubt the taxpayer might have taken the amount of $62,309,546 which it paid to MMBW and instead of paying it to MMBW under the Principal Assumption Agreement have invested it in Commonwealth Bonds maturing at or about the same time as its debentures were to mature. If it had done that it would have derived income which it might then have applied in satisfaction of most, if not all, of its liabilities to debenture holders. Similarly, it might have invested the same amount as it paid to MMBW on more speculative investments and it might then have obtained returns greater than the amount necessary to pay the debenture holders Examination of those other transactions does not reveal whether or when the taxpayer derived income as a result of the making of the Principal Assumption Agreement. In particular, the characterisation of the gains or receipts obtained in accordance with hypothetical transactions of the kind described is of little, if any, assistance in characterising the nature of the benefits identified as flowing from the making of the Principal Assumption Agreement.
205 For these reasons, the Commissioner's cross-appeal on the MLMDQ issue should be dismissed.
